| description | The present invention discloses a motor system without a hall sensing element. The motor system comprises a first output pin, a second output pin, an auxiliary pin, a stator, a rotor, a primary coil, and an auxiliary coil. Both the primary coil and the auxiliary coil surround the stator. The primary coil is coupled to the first output pin and the second output pin. The auxiliary coil is coupled to the auxiliary pin. The auxiliary coil is configured to determine a phase switching time point. The motor system detects the zero point of the voltage of the auxiliary pin, so as to detect the position of the rotor and determine the phase switching time point. |
